Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security device mainly installed in a bank or a convenience store.

[0002]

2. Description of the Related Art In financial institutions such as banks and stores represented by convenience stores, various security measures are taken as measures against robbers and thieves. A color ball is widely known as a crime prevention means as described above, and when the criminal escapes, a clerk or an employee throws at the criminal while aiming at the criminal, and the police arrest the criminal. It was intended to mark when doing. Also,
A special fluorescent paint with high permeability is enclosed in the color ball, and if the color ball ruptures,
The paint inside adhered to the criminal's clothes and skin for a long time.

[0003]

However, since the above-mentioned color ball is aimed at the escaping criminal, accurate control for hitting the color ball is required. Employees and regular customers are often unable to throw colored balls in a calm mental state, due to the unstable mental state immediately after the intruder has entered. From this, the probability of hitting the color ball against the criminal is statistically about 10
Since it was less than a percentage, it was necessary to improve its accuracy.

An object of the present invention is to provide a security device capable of reliably applying paint to a robber or a thief who has entered a store.

[0005]

According to the first aspect of the present invention, there is provided a pressurized paint having an injection nozzle at an entrance and an entrance, and having an opening and closing control means at the injection nozzle. The container is connected via a feed pipe, and by opening the opening / closing control means, paint is sprayed from the spray nozzle toward a criminal passing through an entrance.

Here, the injection direction of the injection nozzle is as follows.
It may be provided toward the opening space of the doorway, or may be provided slightly from the opening space toward the indoor side. The opening / closing control means is not particularly limited as long as it can open the container manually or automatically, and is not particularly limited. For example, an electromagnetic valve that opens a valve in conjunction with a sensor or a container that closes the container is used. And a lever handle having a structure for pulling out a plug that is being pulled out. Further, examples of the container for the pressurized paint include those having a structure in which contents represented by a spray container or a cylinder are sealed together with a high-pressure gas.

With this configuration, if a clerk, an employee, or a general customer opens the opening / closing control means when the criminal passes through the entrance, the interior of the pressurized container is opened. At the same time as the paint is opened, the paint is vigorously sent from the container to the ejection nozzle, and the paint is ejected from the ejection nozzle toward the criminal.

According to a second aspect of the present invention, as the opening / closing control means, there is provided a sensor for detecting passage of an entrance and an operation unit for remotely controlling the operation and stop of the sensor. If the container is provided with an electromagnetic valve having a structure in which the valve element is opened in conjunction with the detection, the sensor is operated from the operation unit, and a signal is transmitted from the sensor when the sensor detects a criminal approaching the entrance. And
Since the electromagnetic valve that receives this signal opens the valve body in conjunction with it, the paint can be applied to the culprit passing through the entrance at a more accurate and reliable timing. The sensor may be provided at any position as long as it can detect an object passing through the doorway.For example, the sensor may be provided at a position above the doorway, such as a sensor of an automatic door, or a floor mat. As described below.

Is a schematic explanatory view showing the process of the operation in FIG. 1, and FIG. 4 is an explanatory view showing a class of the embodiment of the present invention.

First, the entire security device will be described with reference to FIG. The security device of the present invention includes a plurality of injection nozzles 2 provided at intervals along an opening frame 11 of an entrance / exit 1, and a pressurized paint container connected to the injection nozzles 2 via a feed pipe 5. 3, an electromagnetic valve 4 for controlling the opening and closing of the container 3, a sensor 6 for sending a signal to the electromagnetic valve 4 when a criminal is detected, and an operation unit 7 for controlling the operation and stop of the sensor 6. Consists of

The spray nozzle 2 is provided with a paint feed pipe 5 fixedly installed along the opening frame 11, and the feed pipe 5
Are provided at a plurality of locations spaced apart along the longitudinal direction of the device. Further, the tip of the spray nozzle 2 is provided toward the opening space of the opening frame 11, and the paint is sprayed on the culprit passing through the entrance 1. And
Each of the spray nozzles 2 sprays the paint in a mist or linear shape, and the spray state of the paint can be freely switched by rotating the tip of the spray nozzle 2. Here, the material of the feed pipe 5 is not particularly limited, and may be formed of, for example, a synthetic resin or a metal such as an aluminum alloy or copper. The color tone of the injection nozzle 2 and the feed pipe 5 is desirably formed so as to exhibit a color close to that of the opening frame 11 in consideration of the appearance of the entrance 1.

[0012] As shown in FIG.
A cylinder-type container that seals the paint together with high-pressure gas in the internal storage section 22 is used. And in the container 3,
An electromagnetic valve 4 that opens and closes according to a command from the control unit 13 is provided. The electromagnetic valve 4 is fitted to the mouth 25 of the housing 3 with its lower end closing the housing 22.

The above-described solenoid valve 4 will be described in detail. In the case body 14 having a hollow portion 26 having a circular cross section,
The case body 14 includes a valve body 16 that is slidable in the longitudinal direction. The lower end protrusion 28 of the case body 14 is fitted to the mouth 25 of the housing 3, and the lower end protrusion 28 Is provided with an internal supply passage 17 that communicates with the housing portion 22 so as to communicate with the hollow portion 26. Further, an external supply path 15 communicating with the feed pipe 5 communicates with a position facing the internal supply path 17 via the hollow portion 26. And the hollow part 26
A spring 27 for urging the valve body 16 to the other side is provided on one side in the longitudinal direction of the valve. The flow path 18 of the valve body 16 does not match the internal supply path 17 due to the urging of the spring 27. , The valve body 16 is pressed to keep the housing 22 closed. The case body 14 is provided with a pressing-type activation device 20 using a cylinder 23 via an arm-shaped support portion 24. This is because when the control unit 13 receives the signal sent from the sensor 6, it sends an operation command to the activation device 20 via the connection connector 21 and the activation device 20 that receives the command.
However, the projection 19 of the valve body 16 is pressed by the cylinder 23 in a direction against the urging of the spring 27. In response to this operation command, the valve element 16 moves the flow path 18 and the internal supply path 1.

Although there is no particular limitation on the sensor 6, a general infrared sensor is used in the present embodiment. Further, the sensor 6 includes:
It is normally in a stopped state, but in an emergency, for example, by pressing a button of an operation unit 7 installed in an invisible place such as the back side of a cash register counter 9, a wire-type or A signal is transmitted wirelessly, and the sensor 6 is remotely operated to turn on the power. Further, the position where the sensor 6 is installed is, for example,
It may be a position above the upper frame of the doorway 1 or a floor mat laid on the floor surface inside the doorway 1 room. You may. It is desirable that the position where the sensor 6 detects the culprit is located at a position that is almost in front of the entrance 1 by the distance corresponding to the stride, because the reaction and the operation speed required until the paint is injected in the present security device are considered. is there. In this manner, the paint is automatically ejected from the injection nozzle 2 at the moment when the criminal passes through the entrance 1, and the paint is accurately and reliably attached to the criminal.

Here, the operation section 7 may be linked to an alarm device such as police or security. In this way, when the criminal escapes from the entrance 1, a report is also sent to the police and security at the same time, so that the criminal can be cleared more quickly and reliably.

Next, the actual operation of the above-described security device will be described with reference to FIG. (A) First step: The intruder is confirmed to enter the room, and the sensor 6 is operated by pressing the button of the operation unit 7. (B) Second process: The sensor 6 detects a criminal approaching the entrance 1. (C) Third step: The sensor 6 sends a signal to the control unit 13 simultaneously with the detection of the culprit. (D) Fourth step: The control unit 13 that has received the signal sent from the sensor 6 opens the valve body 16 of the electromagnetic valve 4, releases the inside of the housing 3, and sends the paint to the injection nozzle 2. (E) Fifth process: The paint sent to each spray nozzle 2 is sprayed toward the criminal. Through such an operation process, the paint in the container 3 is securely attached to the criminal.

FIG. 3 shows an embodiment of the present security device in which the mouth 25 of the housing 3 is closed with a stopper.
Further, a lever handle 4 from which the stopper can be pulled out.
The container 3 having a structure such as a fire extinguisher provided with a is provided in a place accessible from the cashier counter 9. With this configuration, the moment when the criminal passes through the entrance 1 is determined, and by pulling the lever handle 4, the housing 3
The plug that closes the container is pulled out, the interior of the container 3 is opened, and the paint is sprayed from the spray nozzle 2 toward the criminal in the same manner as the electromagnetic valve 4.
